[Objective]To investigate the anti-proliferative effects of CEP on HCT116 cells and in mouse xenograft model. [Methods]The in vivo anti-cancer activity of CEP was determined with Xenogen bioluminescence imaging in a xenograft tumor model. The cel-based multiple signaling pathway reporter assays were carried out to determine the effects of CEP on these pathways. [Results] CEP inhibited growth of human cancer cells, the IC 50 was 0.8~11.5 μM. CEP induced cellcycle arrest in S and G2/M phase. CEP also inhibited xenograft tumor growth in athymic nude mice bearing HCT116 cells. The xenograft tumor size was significantly reduced upon the treatment with CEP(10 or 20 mg·kg-1 body weight) for up to 3 weeks. Pathway-spe-cific reporter assays indicated that CEP effectively suppressed the NF-κB and MAPK/ERK signaling pathways. [Conclusions] Our results suggest that the anticancer activity of CEP in colon cancer cells may be mediated through targeting NF-κB and MAPK/ERK signaling pathways.

Objective:To observe the general status, the effect of resisting to the aggression of FBL-3 cells and protective immunity of the mice by using leukemia vaccine during the immune reconstitution.Methods:The immune deficiency C57BL/6 mice induced by total body irradiation were reconstituted immunity with homologous splenic lympocytes.The mice were immunized by injecting FBL-3 cells subcutaneously,and then attacked by using FBL-3 cells 7days thereafter.The activities of mice,the percentage of carcinoma formation and the growth status of tumor were observed.The amount of IFN-? in peripheral blood was determined by ELISA to evaluate the magnitude of cell immunity.The condition of cell infiltration in tumor central region and its periphery region was explored by patologic-section.Results:Immune reconstitution could obviously elevate protective immunity on the basis of using vaccine,and the amount of IFN-? was obviously higher.The FBL-3 tumors inoculated thereafter grwe slowly,and significant infiltration of mononuclear cells peri-tumor as well as necrosis of tumor cells were observed.Also,the life time of the mice was prolonged.Conclusion:Immune reconstitution and vaccine can significantly elevate protective immunity

Objective To establish an efficient, simple, low cytotoxicity and cheap transfaction system. Methods We have used the cationic polymer polyethylenimine(PEI) to study transient transfection in MCF-7 cells by testing different conditions, including cell concentrations, DNA concentrations, the ratio of PEI nitrogen to DNA phosphate(PEI-N∶DNA-P) and the time of cells grown in serum-free culture together with PEI-DNA complex. Results The optimized cell concentrations were 2?10 5 cells seeded per well in 24-well dishes 18-24?h before transfection. The DNA concentrations and ratio of PEI-N∶DNA-P are very important for optimal transfection and they affect each other. For 1??g DNA per well, the optimal PEI-N∶DNA-P is about 33∶1, however, as for 4??g DNA, it is 9∶1. The best time of cells grown in serum-free culture together with PEI-DNA complex is about 5-7?h.Conclusion With optimized conditions, we can establish an efficient, simple, low cytotoxicity and cheap transfection system by using PEI.

OBJECTIVE:
To investigate the effect of operation on Benign thyroid nodules with hoarseness as primary symptom.
METHOD:
Twelve patients were underwent the operation of subtotal thyroidectomy and exposing of recurrent laryngeal nerve. We evaluating the effect by fibrolaryngoscope and voice acoustic analysis before and after operation.
RESULT:
All the 12 patients underwent surgery successfully. The hoarseness improved obviously and vocal cords were reactivate. Jitter, shimmer and dysphonia severity index showed significant difference pre and one month after surgery.
CONCLUSION
Benign thyroid nodules could also cause vocal cord paralysis and hoarseness, the effect can be satisfying by subtotal thyroidectomy and exposing of recurrent laryngeal nerve if it can be early diagnosed.

A method for simultaneous determination of 20 Perfluorinated alkyl substances ( PFAS) in animal liver using QuEChERs and HPLC_MS/MS technique was developed. The samples were extracted with 0. 1%hydrochloric acetonitrile and cleaned up with C18 , N_Propylethylendiamine ( PSA ) and graphitized carbon blacks ( GCB ) . The analytes were separated by a reversed phase C18 column and gradiently eluted with a mixed solution of 5 mmol/L ammonium acetate methanol and 5 mmol/L ammonium acetate. The samples were quantified using isotope internal standard and external standard with the matrix matched standard calibration curve method. Good linearity was obtained for all the 20 PFAS at the concentration of 0. 1-10 μg/L with the linear correlation coefficients more than 0. 9995. The limits of detection (LOD) and the limits of quantification ( LOQ) for PFAS were 0. 05-0. 2 μg/kg and 0. 4-0. 5 μg/kg, respectively. The recoveries at three different concentration levels ( 0 . 5 , 2 and 5 μg/kg ) were in the range of 70 . 3% -108 . 1%. The repeatability expressed as relative standard deviations (RSD) was ranged from 2. 1% to 11. 9% (n=6).

Obgective To explore the antimicrobial resistance genotypes and molecular epidemic features of Klebsiella pneumoniae (K.pneumoniae) producing extended spectrum 3-lactamases (ESBLs) in the Pediatric Intensive Care Unit (PICU) of Guiyang Children' s Hospital.Methods Disc diffusion technique (Kirby-Bauer method) and automatic microbiology analysis system were employed to determine the antimicrobial resistance,and Double-disk Diffusion was adopted in the phenotype confirmatory test of ESBLs,and PCR was used to determine the antimicrobial resistance genotypes.Results Among 44 straits of non-repetitive-K.pneumoniae,isolated from the children during hospitalization since April to December of 2013,29 straits (65.9%) were detected.The findings of sensitivity tests showed that 29 strains of ESBLs-producing K.pneumoniae presented a higher rate of sensitivity to carbapenems,cephamycin and quinolones,100% resistance to penicillin and cephalosporins of the first and the second generations.Fifteen non-ESBLs-producing K.pneumoniae presented 100% resistance to penicillin.The rate of resistance to 9 kinds of antibiotics (Ampicillin/Sulbactam,Cefazolin,Cefuroxime,Cefamandole,Cefiriaxone,Ceftazidime,Cefepime,Gentamicin,Aztreonam) in ESBLs-producing K.pneumoniae strains(79.3%,100.0%,100.0%,100.0%,100.0%,79.3%,65.5%,41.4%,79.3%) was significantly higher than that of non-ESBLs-producing K.pneumoniae trains (13.3%,6.7%,20.0%,20.0%,0,0,0,6.7%,0) (x2 =17.54,35.51,28.00,28.00,44.00,24.93,17.30,4.18,24.93,all P < 0.05).In 29 strains of ESBLs-producing K.pneumoniae,3 genotypes were detected respectively:93.1% of SHV (27/29 strains),51.7 % of TEM (15/29 strains) and 37.9 % of CTX-M (11/29 strains).Five forms of genotype distribution were presented:14 (43.8%) strains carrying single ESBLs gene,5 (17.2%) strains carrying 2 types,19 (31.0%) strains carrying 3 types,and 1 strain had not been genotyped.Conclusions ESBLs-producing K.pneumoniae had been epidemic in PICU of Guiyang Children's Hospital,with multiple antimicrobial resistances and diversification of antimicrobial resistance genotypes.

Objective To observe the efficacy of HAG regimen in remission inductive treatment for elderly patients with acute myeloid leukemia (AML) and myelodysplastic syndrome-refractory anemia with excess blasts (MDS-RAEB). Methods The clinical features of 21 cases with AML and 9 cases with MDSRAEB (≥60 year old) treated with HA-G regimen in remission induction were retrospectively analyzed,including the complete remission (CR) rate, efficiency rate as well as their toxicities. Results In 21 elderly patients with AML treated with HAG regimen, the efficiency rate was 66.7 % (14/21), CR rate 47.6 % (10/21).In 9 elderly patients with MDS-RAEB, the CR rate was 55.6 % (5/9). The main toxicity of HA-G regimen was infections secondary to hematopoiesis suppression after chemotherapy. All patients were well tolerated to adjusted regimen. Conclusion The HA-G regimen is much effective in remission induction for elderly patients with AML and MDS-RAEB.
